The effect of a concentrated retraction force on the complete displaced structure

Abstract

It has long been recognized that the contribution of bracing, cladding may be included in the design of steel frameworks. On the other hand, — due to the very sophisticated interaction between frames and bracing, cladding — the theoretical solutions need experimental, numerical verification.The Laboratory of Structural Engineering, Technical University of Budapest in 1976–81 carried out theoretical and experimental investigations on full-scale simple elastic-plastic frames. Our goal is to help the design and refurbishment of structures by comparing the experimental results to the results of the virtual structure, modeled by a finite element software.This time we focus on a horizontally displaced building section consisting of three frames, that was retracted with the use of the cross bracing of the end-frame. Some problems of modeling will be presented.
